I know that OEM is the best option, but I am looking to replace the idle air control valve on my 3.4 and cant justify $225.00 for a part that I am not sure is bad. Is this part available as an aftermarket item? Who is a reputable online dealer for Toyota stuff? Thanks and dont flame me too hard, I am in Costa Rica and it is a major pain to get parts here unless your driving a Hilux. I will be in the states next week and am trying to get some parts together to bring back.
